TvVith the foregoing and other objects in view, the invention consistsof the novel construction.I combination and arrangement of parts, ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modiications canbe resorted to which come within the scope of the claims hereuntoappended.

ln the drawings wherein like reference characters denote correspondingparts throughout the several views Figure l, is an elevation of anelectric shockingl machine in accordance with this invention.

Figures 2 and 3 are sectional elevations.

Figure il, is a top plan broken away.

Referring to the drawings in detail the mechanism ot' the machine issupported by a pair of frame plates l, 2, and between which theelectromagnets 3, 4 are secured. @ne of the magnets is positionedbetween the frame plates at one end and the other between said plates atthe other end. Operatively arranged between 'the frame plates l, 2 andalso between the magnets 3, i is a four pole permanent magnet rotor 5,and which revolves freely within the pole shocks of the electromagnets3, casing 6, is provided to enclose the mechanism of the machine andwhich is provided with a terminal cap 7, and 'the latter is insulatedfrom the body of the casing or machine proper by a plate 8, ofinsulation. rl`he plate 8 is provided with an opening 8 for a purpose tobe referred to.

rEhe electromagnets 3, l, include coils gtlt, connected in series, andwith one end of the winding lgrounded to the machine, as at G, and tieother end connected to the short-circuit breaker 9, as at C. The breaker9, is positioned at the outer side of the plate 2, connected therewith,by a pair of holddevices 9', insulated from the plate f2. i inner end ofthe breaker 9, is reduced, as at 9 and which forms a spring acting on aratchet 5', to be presently referred to. to short circuit coils 3, etand to break the short circuit at predetermined periods. The shaft ofthe rotor, is indicated at 5 and the ratchet 5 is secured to one end ofthe shaft 5 at the outside of the plate The shaft 5 is mounted in theplates l, 2 and projects .from each of them. The ratchet 5 is scoured onthe rotor shaft in a position with relation vided with a ratchet gear 5'arranged outside of the plate 1, and which employ/'ed for the purposelof revolving the shaft 5, so as to revolve the rotor The gear 5' isoperated by a right and left ratchet fork 10, which is operativelyconnected to an operating lever 11, by a hinge joint 10. The friction ofthe joint 10 being so adjusted as to prevent movement between the leverand the fork only when the fork 10 is in contact with the ratchet 5', orduring the power stroke or strokes, and in this connection it will bcstated, that on a forward motion ofthe lever l1, the lower leg of thefork 10 is thrown in mesh with the gear 5', while a rearward or backwardmotion of the lever 11, the upper leg of the fork 10 is thrown in meshwith the gear or ratchet 5. lVhen the motion of the fork 10 is slowerthan the gear 5', the fork is thrown out of mesh and to a central orneutral position, by the ratchet gear 5', but a. motion of the lever` ineither direction, will again throw the fork into mesh, and revolve therotor. The power stroke is in both directions, while the movement of therotor is continuous in one direction.

The lever 11, is in the form of an inverted yoke, and the leg 12, is ofgreater length than the leg 13 thereof. The legs of the lever 11 aremounted on the pivot 14, which is seated in the plates 1, 2. The lowerend of the leg 12 is rounded and is mounted in the seat formed in thefork 10 and which provides the hinge joint. 10. The legs of the lever11. are arranged at the outside of the plates 1, 2' and the leg 13 has acurved spring bearing against the lower end thereof. The curved springis indicated at 11 and acts against the lever 11 to hold it in theposition shown` The top of the lever 11 provides a thumb piece and thelever is actuated by the thumb of the hand in which is holding themachine. As the backward motion of the thumb is the weakest. the spring11 assists the thumb in returning the lever on the back stroke. as wellas securing a more equal thrust on both strokes and less fluctuationrotation. at the same time securing the position of the lever when themagneto is not in operation.

The entire mechanism is enclosed in the casing 6, the latter is formedfrom conducting, but not magnetic material, and which forms the groundedterminal of the machine.

The plate S is secured to the end of the machine or rather casing orcase 6, and the cap 7 is secured against the plate 8, by a holdfastdevice 147, which is mounted at the inner end of a. threaded socket l5,in the cap, and engages with the extension of the brake spring l. 'lheextension of the break spring 9, is imlicated at 16, and is bent toextend forwardly of the platev 8, so that it can be readily engaged bythe hold fast device 14. The threaded socket is employed to enable theattaching to the cap of a conductor (not shown) so that the shockingoperation can be had at points removed from the device. The manner ofsetting up the break spring S, or rather the extension 16, provides acontact with the cap 7, thus the cap T and case 6 form terminals for themachine. The bottom of the case 6, is corrugated, as at 17, tofacilitate holding of the machine.

The manner in which the machine is operated is as follows The machine isheld in the hand with the -ap 7 projecting beyond the hand. Anoscillatory motion is imparted to the lever 11, by the thumb of the handholding the machine, causing thereby the rotor to revolve between thepoles of the electromagnets 3, 4 and setting up an alternating currentin the Windings, and which is periodically interrupted by the breakspring 9, which is so adjusted to break or open the short circuit of thewindings at a time when the current phase is highest, causing aphysiological shock in the external circuit formed by the body. Thefrequency of the impulses is Within the control of the operator, thehigher speed giving the higher frequency and corresponding shock.
